The baseplate 3 is provided with ahole 11 therein in alignment withtheannularopeningii and "the lower sideor bottomof the barrell is'-providecl with a hole 12 111" alignment with the annular opening 10.'saidbarrel "is also provided with upper and lower f 1ot's;1 a and 11respectively.

The bolt=bar 5 "has a r018": 15 *ekten'ding through the body thereof"which may -be'7 brought into alignment with the'hole 11 and opening 9or the'hole' 12 andopeningj it'O 'as desired. Said 'bolt bar 5 "isprovided adjacent the top of the-hole" 15 with a'fshoulder 16. 17indicates a pin extending through 'the'" 7 5" holei15in the bolt-barbadaptedjto'be received 'by the slot 8 in thebarrel land which isprovided with an upper scre'wthreaded end as shownanda lower headed end18. 19 indicates a spring encircling said pin 17 and bearingagainst'the" lower'hea'ded end 18 of the pin and the-shoulder 16=withinthe hole 15, the action of said 'spring'tending, as is obvious, to forcethe 'pin downwardly. 2O indicates "an. operating knob sfi whichisscrewed' on the upper end "of" the pinfl17, the=-lower .end "of whichis of -a diameter P i g t0 j 'fit within: the annular openings 9 a d 910"of the guiding will bear against the bolt bar 5 when received by saidannular openings.

The bolt-bar 5 which-is actuatdbythe operatingknob 20 is showninfprojecte'd'or locked position in Fig. 1 with in this. position theend of the operating 'knob 'fits within the annular opening 10 where itis held by"theactionofthes ring 19 and the headedend 18ofthe pin 1"-.e'X-" tends through the hole'12 in'thebarreli l,

" holding the "ibolt-ba'r" in thereby securely Also. the. operating knoblocked position.

extends vertically upward, asshownywhen the bolt-bar is inprojectedfposition so that" it is then conveniently out of the Way andto become caught in'a persons clothing. To retract the bo'lt so as toopen the door I the 1 operating knob 20 -is pulled upwardly against theaction of the spring a I the endthere-='"95 of extending-within thehousing- 7 When over'the lower slot 14:.

tracting movement well as the headed end of the 1 l engagement with thehole 12.

l1 The oper ing knob is then pressed downwardly to the left, the pin 1.riding in the L-shaped slot 8 and the end of the operating knob earingagainst the barrel a over the slot 8. This movement, as is obvious,retracts the bolt-bar 5 and releases the end thereof from its engagementwith the housing to unlock the door. WVhen the bolt-bar has reached itsextreme retracted position the end of the operating knob automaticallyslips into the annular opening 9 and the headed end 18 of the pin intothe hole 11 due to the action of the spring 19 (see Fig. 4) and thus theboltbar is firmly held or locked in retracted position from which it mayonly be released by pulling up the operating knob against the action ofthe spring. The bolt-bar may then be. thrown into projected position bypressing the operating knob to the right and then upwardly and when itreaches the end of its upward movement the end thereof automaticallyslips into the annular opening 10 and the headed end 18 of the pin intothe hole 12 due to the action of the spring to eifectively hold thebolt-bar in projected or locked position.

To permit the door to be partially opened but at the same time locked insaid partially opened position, which is desirable in some cases as itwill permit the person on the outside of the door to be seen before thedoor is completely opened, I have provided improved and novel meanswhich will now be described.

21 indicates a staple whose base-plate 22 is fastened to the door frame2 by suitable screws as shown. Attached to said staple is a chain 23fastened to a locking pin 24;. having a collar 25, a reduced neck 26 andahead 27. 28 indicates a transverse hole with which the bolt-bar 5 isprovided and which has a diameter sufficient to receive the locking pin24 and its head 27 but not the collar 25. VVhe'n it is desired to openthe door partially the locking pin 24-. is pushed through the hole 28,its movement being limited by the collar 25 which acts as a stop andwhich bears against the barrel 4- VVhen the bolt-bar is retracted byoperation of the operating knob 20 it is first moved through an angle of90, in 'an obvious manner, which accordingly changes the position of thelocking pin 2t'from a transverse horizontal one to a vertical one. 'Afurther opening or reof the bolt-bar by means of the operating knobcarries the locking pin 24; with it, the body thereof sliding within thelower slot 14 and the reduced neck 26 within the upper slot 15 which isof a escapee width sufficient to receive. said neck but not r the head2?. When the bolt-bar has reached its extreme retracted position itbecomes automatically locked in that position as has been described. Thedoor may now be opened partially, the extent of said opening beinglimited by the length of the. chain but it may not be opened fully untiltllocking pin 24 is withdrawn the her thereof 27 contacts and bearsagainst barrel 4 over the slot 15 through which i cannot be drawn. Acomplete opening 0 the door may only be efiected by throwing, the boltbar into locked position, withdraw ing the locking pin 24 from the hole28, and then again retracting the bolt-bar.

What I claim as my invention is 1. In a bolt, a barrel having a slottherein and provided with a hole remote from said slot, a bolt-baradapted to slide within said barrel, an operating knob for actuatingsaid bolt-bar, a pin carried by said operating knob and adapted to slidewithin the slot of the barrel and means for automatically forcing saidpin to engage the hole in the barrel to lock the bolt-bar against movement.

2. In a bolt, a barrel having a slot terminating in an annular openingand provided with a hole registering with said an nular opening. abolt-bar adapted to slide within said barrel, an operating knob foractuating said bolt-bar and adapted to lit. within said annular openingand a pin carried by said operating knob and adapted to slide within theslot of the barrel and to automatically engage the hole in the barrel tolock the bolt-bar against movement.

3. In a bolt, a barrel having a hole and a slot therein, a bolt baradapted to slide within said barrel and provided with a hole r extendingthrough the body thereof adapt ed to register with the hole in thebarrel. operating knob for actuating said bolt-bar, a pin carried bysaid operating knob adapted to slide within the slot and extendingwithin the hole in the body of the bolt-bar and a concealed springadapted to automatically project said'pin into the hole of the barrel tolock the bolt-bar against mo vement.

4. In a bolt, a barrel having a hole and a slot therein, a bolt-baradapted to slide within said barrel and provided with a hole extendingthrough the body thereof adapted to register with the hole in thebarrel. a shoulder on said bolt-bar adjacent said hole, an operatingknob for actuating said boltbar, a pin carried by said operating knobadapted to slide within the slot in the barrel and extending within thehole in the body of the bolt-bar, a head on said pin and a concealedspring encircling said pin and engaging the head thereof and saidshoulder pin connected with the and adapted to automatically projectsaid pin into the hole of the barrel to look the bolt-bar againstmovement.

5. In a bolt for a door, a barrel, a boltbar adapted to slide withinsaid barrel and detachable means adapted to extend through said bolt-barand interlock therewith to permit the door to be partially opened only.

6. In a bolt for a door, a barrel, a bolt-bar adapted to slide Withinsaid barrel and means fastened to the door frame and detachably securedto the bolt bar and adapted to interlock with said bolt-bar and saidbarrel when said bolt-bar is in retracted position and to permit thedoor to be partially opened only.

7. In a bolt for a door, a barrel, a boltbar adapted to slide withinsaid barrel and provided with a hole therein and a lookin door frame andadapted to be inserted in the hole in the bolt-bar and to engage thebarrel to permit the door to be partially opened only.

8. In a bolt for a door, a barrel having slots in the end thereof, abolt-bar adapted to slide within said barrel and provided with a holetherein, a removable locking pin connected with the door frame andadapted to slide in the slots in the barrel and to be inserted in thehole in the bolt-barand a head on said locking pin adapted to engage thesaid barrel.
